This procurement is for the supply of Global Navigation Satellite System (GNSS) data from co-located at tide gauges to enable better measurement of sea-level rise (SLR) and calibration of the equipment. The purpose of the supply of GNSS data will give us indication of the deformation at tide gauges to see if there is any wider movement that is affecting the long-term monitoring of sea level.

LINZ is preferably looking for a single supplier to provide, install and maintain GNSS equipment in the vicinity of six long term tide gauges and refurbish four of the existing GNSS stations which are already co-located at tide gauges, as follows:
a) The new sites will need to be located in the vicinity of the following six tide gauges: Moturiki Island, New Plymouth, Napier, Nelson, Jackson Bay and Bluff,
b) The existing sites are located at Auckland, Wellington, Christchurch and Dunedin.

The Services will include:
1) Provide, install and maintain equipment at the 6 new sites (including communication equipment),
2) Assess long term suitability of the 4 existing sites,
3) Replace and perform maintenance on infrastructure at the 4 existing sites, including replacing GNSS antenna, receiver, and other equipment which has reached end of life or is not delivering according to Part 6 - Specification for Continuously Operating Reference Stations.
4) Regular supply of GNSS data from these stations to LINZ,
5) Annual calibration of the tide gauges as per Part 7 – Specification for Tide Station v1.0,
6) Annual levelling between benchmarks and tide gauge and GNSS station, and
7) Associated health and safety checks.

We expect the installation of the new GNSS sites and refurbishment of existing sites to be completed by July 2024.

This tender has been awarded.
